ALARM APPARATUS.

To all whom it may concern:

Be it known that I, FRANK PESCE, a subject of the King of Italy, andresiding at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Alarm Appa"atus, of which the following is a specification, such as will enablethose skilled in the art to which it appertains to make and use thesame.

T hisinvention relates to alarm apparatus designed for use in a sleepingroom or compartment and to be set so as to sound an alarm at apredetermined time so as to awaken a party or parties sleeping in saidroom or compartment; and the object thereof is to provide an improvedapparatus of this class constructed and adapted to be operated so as toawaken, if desired, only one party without awakening or arousing otherswho may be sleeping in the same room or compartment or adjacent thereto;a further object being to provide an alarm apparatus of the classspecified which will operate intermittently through a given length oftime; and with these and other objects in view the invention consists inan apparatus of the class specified, constructed as hereinafterdescribed and claimed.

My invention comprises an ordinary clock. a battery, and an electricbuzzer or bell, the mechanism of the clock being the same as that o'tall ordinary clocks except as modified to adapt said clock to thepurpose for which it is intended and as will be hereinat'ter fullydescribed; and the battery is an ordinary battery placed in a pedestalor casing on which the clock is mounted and the buzzer or bell is inelectrical connection with the mechanism of the clock and with thebattery by means of circuit wires which are of suflicient len th toenable it to be put under the pillow of a bed or in any other desiredposition.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawing forms a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which Figure l is an elevation showing mycomplete apparatus and showing the method of its operation, part of theconstruction being broken away; Fig. 2 a side view of the clockmechanism only part of which is shown, and part being in section; Fig. 3a plan view of Specification of Letters Patent.

Application filed August 3, 1909.

Patented Mar. 22, 1910.

Serial No. 510,965.

said mechanism also showing only part of the mechanism and parts beingbroken away; Fig. 4 a view similar to Fig. 2 but showing the parts in adifferent position; Fig. 5 a side view looking in the direction of thearrow 5 of Fig. 3, and showing only part of the clock mechanism; andFig. 6 a side view of the clock and the pedestal or base on which itstands and looking in the direction of the arrow (3 of Fig. 1.

In the practice of my invention, 1 provide a pedestal casing a on whichis secured a clock 6 having a bottom portion 6 and in the pedestalcasing 64 is placed an ordinary dry battery 0 with which is connected bycircuit wires (Z and c an ordinary electric buzzer or bell f. The clockZ) is of the usual construction and comprises a framework in, or inconnection with which, the clock mechanism is mounted, and whichcomprises a bottom or base member 9, corner posts and parallel :t'rameplates g That part of the clock mechanism shown comprises a centralarbor 71 on which the minute hand 71,2 is mounted; and a sleeve hmounted on said arbor and. movable longitudinally on the arbor h andwith which the hour hand 70* is connected. The arbor h and sleeve 7r"are passed through. the dial plate h of the clock and the minute andhour hands are on the outside of this plate in the usual manner, andmounted on the sleeve 7L3 between the dial plate and the hour hand It isthe alarm setting hand it provided at its free end with an outwardlydirected finger or handle piece 7L7. ting hand 7 through which thesleeve 7& passes is provided with a short hub h which passes through thedial plate its, and on the inner end of which is secured a disk It, andthis disk h is provided with a backwardly directed pin 2'. Mounted onthe sleeve 72 inwardly of the disk It is a gear wheel 7?, the face ofwhich adjacent to the disk h is provided with a hub 6 and the side orface of the hub adjacent to the disk 71,9 is provided with a recess 2'adapted to receive the pin 2', all of these parts being of the usualconstruction and forming no part of my invention. I have also shown aty' the spring by which the clock mechanism is driven, and at j f, j", 7'j, f, i and j the usual train of gearing of a clock of this class. Ihave also shown at is the escapement which operates in connection withthe balance wheel 70 and the escapement wheel 10*, and with The head ofthe alarm set this construction it will be observed that the movement ofthe wheel j is controlled by the escapement operating through the wheels7%, j and 7' and the shaft k, to which the wheel 7' is secured, isprovided with a finger 7c. The clock mechanism also comprises thegearing and other apparatus by which the hour hand 71. is operated, andthese consist of a pinion m on the main arbor h, a shaft m mountedadjacent to said main arbor, a gear at on said shaft and operating inconnection with the pinion m, and a pinion m on the shaft m andoperating in connection with the gear 2' This part of the mechanism alsocomprises a spring arm a secured to one of the frame posts 9 and ranginginwardly diagonally of the clock mechanism and provided with a head athrough which the main arbor 7L loosely passes and the head of thespring arm n is provided with a supplemental arm n which projectsapproximately at right angles to the arm a. All these parts being oldand well known in connection with alarm clocks. I also, in practice,secure to two opposite frame posts at one side of the clock mechanismtwo inwardly directed spring contact arms 0 and 7), the inner free endsof which overlap. The inner end of the arm 7) is set inwardly from thecorresponding end of the arm 0 and is preferably provided with a softmetal contact plate 2) and the inner or free end portion of the arm 0 isprovided with a longitudinal slot or opening 0 through which the finger70 of the shaft 0 is adapted to pass.

One of the wires 0 leading from the battery c is in electrical.connection at 1: with the spring contact arm 7 and the other wire d fromsaid battery is connected with a binding post 0 in one side of thepedestal casing 64 on which the clock 6 is mounted. The wire 6 which isconnected with the buzzer or hell 7 is also connected with the bindingpost 0 and the other wire (Z of said buzzer or bell is connected withanother binding post (Z in the side of the pedestal casing, and the saidbinding post (Z is in electrical connection with a contact point (Z of aswitch secured to, or in the side of the pedestal casing a, by means ofa short wire (i and pivoted adjacent to the contact point of the switchis a switch arm (Z with which is connected a wire 0 which is secured at(Z to a spring contact arm (Z pivoted to one of the frame posts 9 andranging inwardly and terminating above or outwardly of the end of thesupplemental arm 12. The arms a and d are insulated from the frameworkof the clock mechanism as are also the spring contact arms 0 and 7) asshown at r, and the operation will be readily understood from theforegoing description when taken in connection with the accompanyingdrawing and the following statement thereof.

The clock operates in the main, the same as all other clocks of thisclass and, in practice, the alarm hand A. is at the time atwhich it isdesired that the alarm shall opcrate, and it will be imderstood that thegear 2' revolves but once in twelve hours, and when this wheel reaches apoint at which the pin 2' of the disk 71 is opposite the cess in saidwheel the spring arm n. operates to move the gear 11 outwardly so thatsaid pin will enter said recess. and at this time the supplemental arm amoves outwardly and makes contact with the end of the spring contact arm(Z It will be understood that the shaft is continually rotated and thefinger Z1 thereof continually throwing the free end of the contact arm7) into connection with the free end of the contact arm 0 but thisoperation produces no result until the supplemental arm n is thrown intoconnection with the contact arm (Z as above described, and when this isdone the making and breaking of the connection between the contact armso and 7) makes and breaks the circuit as will he understood. \Vhen,however, the tinger .51" is pressed against the inner end of the arm 71it forces said end of said arm out against; the end of the arm 0 andholds it in connection therewith until the said finger slips otf of theend of the arm 7) and passes: through the slot or opening 0 in the arm 0and during this time the bell or buzzer 7' is operated. The arm 71;revolves approximately about once a minute and the arms 0 and 7) willtherefore be thrown in contact approximately every minute, and thisconnection continues for eight or ten seconds during which time the bellor buzzer is operated. This intermittent operation of the bell orbuzzer, or the intermittent connection of the arms 0 and y) willcontinue until the pin 2' moves out of the recess 2 in the hub 2'" ofthe wheel 2' which operation breaks the con tact between thesupplemental arm m and the arm (Z and this period of time depends on thecircumferential extent of the recess 2" in the hub 2' and this with theconstruction shown would be approximately one hour.

It will be understood, of course, that in order for the apparatus tooperate as above described the switch arm (Z must be closed so as toclose the circuit in which the hell or buzzer is placed and theapparatus may be thrown out of operation at any time by opening theswitch arm as shown in Fig. 6.
